Dense fog reduces your view. Which headlight setting is appropriate?
Correct answer: Low beams, with speed reduced to fit visibility.
High beams reflect back from fog and can worsen glare. Use low beams, slow down, and leave additional room.

Snow or heavy rain makes traction uncertain. What should you do with cruise control?
Correct answer: Leave it off and manage speed yourself for the conditions.
The manual advises against cruise control in bad weather. Direct, smooth speed control is important when traction changes.

A snowplow ahead creates a cloud that hides the road and its equipment. What should you do?
Correct answer: Stay well back until you have clear visibility and a safe opportunity.
Snowplows have limited visibility and equipment wider than the visible vehicle. Do not drive into the snow cloud or attempt a shoulder pass.

Tall crops block your view of a rural intersection. You see no dust from another vehicle. What should you do?
Correct answer: Slow and approach cautiously; no dust does not prove the road is clear.
Vegetation and terrain can hide crossing traffic. The absence of a dust cloud is not reliable evidence that nobody is approaching.

A queue beyond a railroad crossing leaves no room for your entire car. The gates are up. What should you do?
Correct answer: Wait before the tracks until you can clear them completely.
Never enter a crossing unless there is room for the entire vehicle beyond it. A signal that allows crossing does not make the tracks a waiting area.

Your car becomes disabled on the tracks, even though no train is visible. What is the first priority?
Correct answer: Get everyone out and well away from the tracks, then call the posted railroad emergency number or 911.
Move people away from the crossing immediately. The blue emergency notification sign provides a railroad phone number and crossing identifier; use 911 if that information is unavailable.

Your headlights suddenly go out at night. After trying the controls, they still do not work. What should you do?
Correct answer: Use available warning lights and leave the roadway safely as soon as possible.
A car without usable headlights is unsafe to continue driving after dark. Warn other traffic and move to a safe stopping place.

Your car develops trouble but can still reach a safe pull-off. Where should you stop?
Correct answer: Well out of traffic where approaching drivers can see you.
Use warning lights and choose a visible location safely clear of traffic. A blind curve or hill can hide the disabled vehicle from approaching drivers.

In a car without ABS, heavy braking locks the wheels and the car starts to skid. What should you do?
Correct answer: Ease off enough to regain grip, then reapply controlled braking.
Locked wheels reduce your ability to steer. Restore rolling traction and brake without locking them again; this is different from the steady-pressure procedure for functioning ABS.

Ahead is a bridge with an open metal-grating surface. How should you adapt?
Correct answer: Reduce speed, hold the wheel firmly and increase the gap ahead.
Open grating or steel can reduce braking and steering traction. The guide advises lower speed, a firm steering grip and more following distance rather than aggressive corrections.
